I use armor. I have no issue with my other game. I use chrome and I have ran cleaner. No option to sign into paypal so it is like the transaction is not recognized at all. Its bizarre which is why I came to support. Thx for the attempt, Like u say, nothing out of pocket lol.
on Armor, when you make a purchase with the game an additional dialogue window opens, if you're in full screen you may not notice, try popping out of fullscreen, start the purchasing process and see whether another tab is opened with the paypal interface where you enter your details,
it's kinda hiding behind the tab the game is loaded on,
it's been a while since my last purchase on Armor but I'm sure it's summit like that, last year I bought keys for the anniversary boxes and a discounted dmu, it took a bit for me to remember how the process went!
is Chrome working ok for you? most peeps get the unsupported video card warning and lots of lag cos it started rendering in software mode, there is a Chromium you could install that predates the changes to Chrome,
have a look at this link,
